Master disc recording apparatus and method for recording data on different types of master discs

摘要

A data block of digital data, which is to divided into a plurality of data blocks, is input to a transfer rate changing apparatus from a data transferring device at a first transfer rate each time when a transfer instruction signal is supplied to the data transferring device. The transfer rate changing apparatus is provided with: a memory device for storing the data block at the first transfer rate, which is transferred from the data transferring device, and outputting the stored data block at a second transfer rate, which is different from the first transfer rate; and a controlling device for supplying the transfer instruction signal, which instructs the data transferring device to transfer one data block to the memory device, to the data transferring device when the memory device finishes outputting another data block which has been transferred from the data transferring device prior to the one data block.
